IMPROVEMENT IN SPRING BED-BOTTOMS.

The Schedule referred to in these Letters Patent `and making part of the Same.

To all whom it may concern:

'Be it known that I, GEORGE SPEGKNER, of Madison, in the county of Dane and State of lWisconsin, have made certain new and useful Improvements in Spring Iedflottoms; and I do hereby declare the following to be a full, clear, and exact description of they same, reference being had to the accompanying drawing forming part of this specification, in which- Figure l is a plan view of a bed-bottom constructed in accordance with my invention, and

Figure 2 is a vertical section of part of the bedbottom.

Similar letters of reference in the drawing indicate corresponding parts.

My invention has for its object to improve the con struction ofspring bed-bottoms, whereby the saine are'rendered more ecient and durable; and to this end,

It consists in the method of' constructing the springs and in connectingl them together and tothe frame, which I will now proceed to describe in detail.

In the accompanying drawing the frame of the bedbottom is shown, consisting of the side rails or bars A, .the transverse bars or slats B, which support' the springs and the end bar C, to which the whole series of springs is attached.

' The end bars are supported above the bars A B ona level, or nearly so, with the top of' the springs, by-

4 means of the short posts) and braces E. n F are the spiral springs,`secured to the slats B by means of the short bands or loops g, as shown. The springs are constructed in pairs from one piece of wire, so as'to leave loops, H, between the springs of each pair. .lhe springs of each pair are placed be side each other upon the same slatl,l as shown.

Clusters of four springs are formed' by connecting the loops of two pairs, placed opposite each other upon separate slats, by means of the loops or bands I, and each cluster of four is-connectcd to the next cluster upon one side by means of the cross-loop or y band J,

and upon the other side by means of the short loop By this arrangement ofthe springs the bed-bottom is made more eiicient, because the springs sustain each other, and at the same time preserve their independent action. Such is theconnection of parts also that a mattress placed upon the series of springs is supported at all points, and prevented fromworking in between the springsV to disarrauge the latter and render the bed uneven. v The series of springs is attached to the end' bars O by means of loops N, 'which tit over or within staples.

secured to the edges of the bars.

By this construction the springs are permitted tq rise and fall without hindrance atthe end ofthe seriesl My improved springs are constructed with the smallest coil or spiralbelow the center of the spring, or nearer one end than the eimer, whereby the upper portion of the spring is rendered moreexible and the lower portion stiffer and more durable.

By my invention a spring bed-bottom is produced in which the springs retain their independent` action without the possibility of lateral displacement.

Having thus described my invention,

What I claim as new thereimand desire to secure by Letters Patent, is-

In combination with the spiral springs F, constructed in pairs, the connecting-loops H, I, 2T K, and N, all arranged as described, for the purpose specified.
